One big advantage Android tablets have over the iPad is the ability to display dynamic information on any of the home screens. While iOS is limited to displaying numbers on icons to indicate new emails or notifications, Android's app widgets can display live details on your smartphone or tablet screen, which is much more useful. On Android tablets, the larger screen has room for scads of live widgets, letting you create a rich personalized information dashboard.
I've been using widgets on Android OS 3.x (Honeycomb) tablets for the last year. Following are some hints and tips based on my experiences. (The screen shots are of a Samsung Galaxy Tab 10.1, which has a Samsung TouchWiz graphical interface.)
My Android tablet has five home screens, two of which I set up with widgets to stream live information. For the first screen I see when I turn on my tablet (see below), I set up personal and local information widgets, including my email, calendar, and weather. I also set up widgets for Evernote, Google Docs, and the note-taking app SpringPad. Facebook, Google Voice, and Twitter (which I access via TweetCaster Pro) all have their own widgets. However, I didn't feel the need to see streams for these apps on my home screen. So I just set up simple launch icons for these apps down the right side of the screen, along with the icons for my Web browser and the tablet's camera.
Android widgets can show continuously updated data for your inbox, calendar, Google Docs, and other useful apps.
Tapping any email subject line or calendar event in the widgets launches the app and takes you to the associated message or event. You can even initiate a new email message by tapping the message creation icon that's in the upper right corner of the Gmail and email widgets. Note that while Gmail has a dedicated app, Android's email app can deal with most other common email server types such as IMAP3, POP3, and Exchange ActiveSync.
I set up a second home page to be my news and shopping dashboard. I put up a trio of news widgets--News Republic for Tablet, Reuters News Pro, and USA Today for Tablet, and set up widgets for Amazon MP3, Dictionary.com, and Google+. Oddly, Google's own Play Music service doesn't have a widget.
News apps are popular widgets. In fact, any data that works well in an RSS feed works well as a widget.
If you don't like widgets cluttering your screen, you can see a lot of your notifications in a list instead. Android's notification list pops up from the bottom right of the screen. You can set up notifications for Facebook, Twitter, Skype, email, weather, and other push-information apps.
Android's notification list is an alternate way to display data for some apps. You might prefer it if widgets take up too much of your screen.
How to place widgets
To place a widget on a home screen, press and hold any unused area of the screen. This action displays objects that can be added to a home screen, including widgets, app shortcuts, wallpapers, and app-specific action triggers such as creating a WordPress blog item.
Adding a widget is a simple matter of choosing one from the list that's displayed at the bottom of the screen. Some widgets are available in different sizes. Selecting a widget places it on the screen where you performed the tap-and-hold action. Another way to add a widget is to simply drag it from the list to a home page.
To add a widget to a home page, press and hold the spot where you want it to appear. Then choose the widget from a list.
